LOOKING VALVE FOR GASOLINE ENGINES.

Application filed. June 4,

My invention relates to improvements in looks for internal combustionmotors and for gasoline engines to control the flow of the gasoline inthe mechanism and to provide a simply constructed, operated andaccurately effective device for controlling the fuel circuit whichfurnishes fuel for the motor and which will effectually preventunauthorized removal of an automobile or the like.

WVith these and other objects in view, my invention consists in certainnovel features of construction and arrangement of parts as will behereinafter fully described and pointed out in the claims, referencebeing had to the accompanying drawings in which:

In carrying out my invention, I provide a tubular casing A, in which isremovably and slidably mounted the lock shaft B and the compressionspring 2, contacting with and supporting the shaft. The tubular casing Ais surmounted by the tumbler box or chamber C. Mounted in the lower endof shaft B, I have the plunger rod 3 and mounted on its lower end, Ihave the gate 4, adapted to be seated in the valve D, mounted at anyconvenient point in the gasoline conduit or tube E. At the base of theinterior of easing A, I have a shelf 6, and between shaft B and shelf 6and surrounding the plunger rod 3, I have the coiled spring 2, restingat its lower end on shelf 6. In the upper portion of shaft B and on theinner side thereof, I have the series of recesses 2, 3', 4, 5', 6, 7, 8,9, and 10. Mounted on said casing A, as before described, I have thetumbler box or chamber C, held in position by set screw y in casing C.The upper end of shaft B is slidably mounted in cham- 1923. Serial No.643,429.

ber C, its upper end at 7 may be reduced in size or not and has slidableconnection thru the opening 8 in the top of chamber C. ()n the innerside of shaft B I have the recess 14 for governing the sliding move mentof the shaft B and in casing A, I have countersunk the screw 15 enteringrecess 14. Itemovably mounted in chamber C, I have the shaft 9, havingthe screw cap 9 and threaded end 10 and mounted on the upper and lowerends of shaft 9, I h ve the wash ers 11.11 in which are mounted the setscrews 1l.11. Within the interior of chamber G, l, have pivotallymounted on shaft 9, a series of tumblers, a, a, a, b, 6, Z) and 0, 0 andd, plan views of which are shown in Figs. 5, 6, 7, S, 9 and 10 andprojecting from the inner edge of the same, I have the series of tumblerlugs a, a", a, Z), L, b, 0, c and d, as shown in Fig. 3, adapted toremovably enter the recesses 2 to 10 in the side of shaft B. Projectingfrom the outer edge of each of the tumblers, I have the operating handle13. This designation has also the letter mark of its tumbler, such as13, 13" etc. It is to be noted that these tumblers are of right, leftneutral and pivot variety, as shown in Figs. 5, 6, 7, 8, 9 and 10, theright hand tumblers shown in Fig. 9, the left-hand tumbler shown in Fig.7 and the neutral tumbler shown in Fig. 8, also the pivot tumbler shownin Fig. 10. The pivot tumbler shown in Fig. 10 on its inner edge has aprojecting lug formed by cutting away the tumbler edge 011 each side oflug in slanting alinement, forming a clearance space on each side oflug, the tumbler having on its outer edge a projecting key handle 13 Inmy invention I have mounted a plurality of right-hand tumblersdesignated by a, a, u and left-hand tumblers designated by b, b, 7) andneutral tumblers designated by 0, c and pivot tumbler d. The number ofeach, vary according to the combinations to be made. These tumblers areequal in thickness and diameter and thus are interchangeable so as topermit of a great variety of combinations. In the chamber or tumbler boxC, I have the face opening 12 and projecting from each tumbler, I havethe operating handle 13, designated in the groups of tumblers in Fig. 2and Fig. 3 as operating handles 13, 13 13 13 13 13 13", 13 13, and 13which said operating handles being positioned to project in alinementthru opening 12 in chamber C, as shown in Fig. 2 and I there designatethe right-hand operating handles as 13 13 and the left-hand operatinghandles as 13, 13 While the neutral operating handles are designatedas13 18, and pivot operating handle as 13. At any convenient point in thegasoline conduit E, I mount the valve D, having therein the valve seat5, adapted to receive and seat the gate at. In tumbler chamber C on theopposite side from the opening for the operating handles I may or maynot have an open face and in mounting my device, it may be a tached inany convenient manner to the body of an automobile or other structure,where the "same is to be used, in convenient position for operating thekeys 13 and etc., while casing A extends down to and is securely mountedin the valve casing D.

In the operation of my device, the tumbler chamber and connecting valvecasing C being securely mounted in valve D on gasoline conduit E, Iarrange my combination of tumblers as I desire, by unscrewing andremoving shaft pin 9 in the tumbler chamber and removing the tumblersfrom the chamber or case. Having arranged the group of tumblers asdesired for the combination, I replace them on pin 9 in chamber C andfasten pin 9 in place. The tumblers are so mounted and fitted, that byturning the right l'iand tumblers to the right and the left-handtumblers to the left, the lugs a, a, b, b, c, e, a, b are removed fromthe recesses 2 to 10 in shaft B, now held in locked position with gate 4in seat 5. By turning the tumbler lugs out of engagement with recessesin shaft B the compression coil spring 2 being thereby released frompressure of the lugs it expands and raises shaft B and with it gate 4and shaft head 7, and the conduit is open and is held open by theexpanded spring 2. By again turning or moving the key tumblers, any oneor more of the lugs 0;, 0;, b, b, 0, c, a, b of the tumblers enter thecorresponding opposite recess in [shaft B and are in engagement with theshaft and the shaft thus is locked in raised and open position and heldopen by the engagement of the lugs a, a, b, b, c, 0", a, 6. hen I desireto close the valve and lock it, I again grasp the operating handles andturn the tumbler lugs out of engagement with the recesses and then pressdown on shaft head 7 until the at is in its seat 5 and I then again turnin the tumbler lugs by moving the operating handles 13 13 etc. andthereby place the tumbler lugs in engagement wi th the recesses 2' to 10in shaft B and lock it and the valve in closed position. Assuming thatthe valve is locked, to unlock it, it is necessary to turn a portion ofthe tumblers to the righthand side, a portion of the tumblers to theleft-hand side and a portion to the center of the key opening 12, thruwhich the operating handles project and the released coil spring raisesthe gate l into open position. The number of handles to be turned to theright, left or center would be governed by the combination that the lockwas set to, for example: Assume a combination of tumblers in which a anda to be turned to left, 6 to the right, 6 to the right, 0 and c to thecenter, d to right or left, a to the left and 'Z) to the right I moveoperating handles 13, 11-5 to the left, I3", 13" to right 13 13 tocenter and turn 13 to left or right and 13 to left, and 13" to right, inwhich position the lock will open. Being in that position, by thiscombination, the recesses in shaft 15 are free of tumbler lugs, thepressure on spring 2 being released, its er;- pansion will force shaft 3upward and raise gate t of the valve 5, thereby allowing a free flow ofgasoline in the gas line E. To close and lock the valve, I press downwith the linger on shaft head 7 of the lock shaft 15, thereby closinggate atof valve D; I then throw the tumbler keys to either side in anymanner whatsoever and the valve gate l is held in closed, lockedposition in valve D, thereby completely stopping the flow of gas inconduit E, beyond or ahead of the valve D. Thus it is observed that anyperson can close the valve and lock it. Now, assuming that the valve isopen, to hold it locked in an open condition and to guard againstpromiscuous closing of the valve D, I turn the tumbler keys in anyposition which will cause one or more lugs to be in inesh in the recessin the lock shaft B, thereby locking the valve open and therebypreventing any person, not familiar with the combination, from closingthe valve. Thus it will be seen that the valve is controlled by the lockshaft in both open and closed position. Thus it will be seen too, that alarge variety of combinations can be formed for controlling the lockingand unlocking of the valve I). To arrange a new combination, I removethe set screw 1 in casing C, contacting with side of shaft B and removethe lock casing C and then loosen and remove the tumbler pin or shaft 9,the tumblers being interchangeable and thus being free to change in anymanner desired the right-hand tmn-blers can be made left-hand tumblersby turning them over and mounting them again on pin 9 and therebyreversing the position of the tumbler lugs, also neutral tumblers can bemoved to any position up and down on pin 9 or brought together in agroup or separated by aright or lefttumbler between them up and down onpin 9, the line of assemblage, thus concealing the exact location of theneutral tumblers.
